Abstract

Introduction: Traumatic extradural haematoma (EDH) is one of the neurosurgical emergencies in the paediatric population. One of the rare complications of extradural haematoma is adjacent parenchymal infarct from the compressive effect of haematoma leading to further morbidity. We aimed to evaluate the incidence and outcomes of this rare complication in paediatric trauma patients.

Methods: We undertook a retrospective review of all operative extradural haematoma cases in single centre paediatric neurosurgical unit between the years 2008 and 2024. Cases with postoperative imaging were analysed for demographics, age, sex, dimensions of haematoma and underlying infarct, pre-operative GCS and pupillary abnormality and time interval from scan to surgery. Infarct was defined as well-defined parenchymal hypodensity corresponding to vascular territory and not attributable to contusions on postoperative CT head performed at 24-72 h. All patients suspected of stroke had further MRI brain for evaluation. Statistical analysis was then performed comparing groups with and without infarct.

Results: Overall, 115 cases of extradural haematoma were identified during the study period. Eighty cases had adequate postoperative imaging to allow assessment for infarcts; 7.5% demonstrated evidence of infarct underlying extradural haematoma. Mean age in the infarct group was 1.8 years (M:F ratio 2:1) with mean EDH dimensions of 77 mm × 31.4 mm × 79.7 mm). Mean age in the non-infarct group was 8.6 years (M:F ratio 2:1) with mean EDH dimensions of (57.5 mm × 19.6 mm × 62.6 mm). Children with infarcts were significantly younger with larger haematoma dimensions and had a higher proportion of pupillary abnormalities. There was no significant difference in pre-operative GCS and scan-to-surgery time-lapse between the groups with and without infarct.

Conclusion: Compressive effect of EDH can lead to underlying parenchymal infarct. Children with extradural haematoma-related infarct were younger with larger haematoma size and a higher proportion of pupillary abnormalities.
